Blair Campbell is a genius, a child prodigy. She has been writing computer code since she was seven and created her first virus at age ten. Computers and the Network are a much larger part of Blair's world than they are of Michael or Erin's.

The problem is, Blair knows this. She's obnoxious, thinks highly of herself and is somewhat tactless. She's not incapable of being friendly, but is a lot more likely to make a sarcastic comment. No matter how intelligent she is or how strong her attitude, though, underneath it all Blair is still an insecure child.
